Title: Method of casting
IPC: B22D17/32
Filed: 1964-08-17
Abstract: 1,014,707. Casting machines. EATON MANUFACTURING CO. Aug. 17, 1964 [March 5, 1964], No. 33618/64. Drawings to Specification. Heading B3F. A method of casting metal which expands as it solidifies in a multi-part mould of similar metal, comprises the steps of pouring molten metal into the mould while maintaining a clamping pressure on the mould parts, then cooling, and while the casting is undergoing expansion as it is cooled, maintaining a reduced holding pressure on the mould parts which will permit them to move apart due to the expansion of the casting but maintain the mould parts in supporting engagement with the casting. The mould is closed by an hydraulic cylinder under relatively low fluid pressure which before filling is intensified by a differential piston. A predetermined time after filling, a timer operates solenoid valves to release the intensified pressure so that the mould is held closed by the relatively low pressure which yields to the expansion of the casting and allows the mould to open slightly.

Title: Apparatus for checking the speed of rotating bodies
IPC: G01R35/04
Filed: 1947-12-22
Abstract: 649,341. Calibrating electricity meters. YORKSHIRE ELECTRICITY BOARD, and MELL, R. E. Dec. 22, 1947, No. 33790. [Class 37] [Also in Groups XIX and XX] Apparatus for checking the speed of rotating bodies having markings thereon comprises an optical refractor device through which the markings are viewed or projected, rotated at a controlled speed about an axis at right angles to the line of view or projection and at right angles to the general direction of movement of the markings, so that when the speed of the body is in correct relationship to the controlled speed, the image of the markings will appear stationary. The described embodiment relates to apparatus for testing electricity meters, in which a beam of light is directed on to markings at the periphery of the meter disc 6 and reflected to pass through a lens 10 and a rotating refractor device 8, whereby successive stationary images of the markings are directed, with the aid of a mirror 20, on to a screen 11 and are observable through an aperture 22. The device 8 consists of two rectangular prisms arranged at right angles to each other and with their ends screened so that they come into operation alternately. It is mounted on a shaft 9 having a splined or like portion for an axially slidable sleeve 31 adjustable for changing gear by a knob 16. A synchronous motor 18 is driven under the control of a sub-standard meter as described in Specification 569,940 and drives through gears 25, 23, 24 (interchangeable according to the type of meter under test), a shaft 40 with gears 42, 43, 44 co-operating with gears 32, 33, 34 respectively, on the sleeve 31 to provide various gear ratios in accordance with the various loads to which the meter under test is subjected. Moreover, through a gear 50, lay-shaft 51, gears 52, 53, 54 and normally inoperative differential 57, further gears 45, 45a can be brought into co-operation with gears 34, 35 on the sleeve 31 to provide further gear ratios. In order to compensate for small fluctuations in the movement of the meter disc with small loads on the meter, a control knob 61, Fig. 1, coupled to a lever 62 operates through a Bowden cable 63 an arm 641, Fig. 4, on a shaft 65 carrying a sector 66 engaging a pinion 67. This movement is transmitted to the planet carrier' 58 of the differential gear 57, whereby the movement of the sleeve bearing the gears 45, 45a and driving through gear 35 or 34 the refractor device 8, represents the algebraic sum of the movements of the gear 55 driven from the synchronous motor 18 and the manually-driven gear 67. During a pre-arranged period (e.g. a single rotation of the meter disc) the control 61 may be operated in this manner to maintain the image on the screen 11 stationary. The position of the pointer at the end of the period will then indicate the amount of discrepancy.

Title: Improvements in or relating to means for holding electric lamps
IPC: H01J5/50
Filed: 1933-12-01
Abstract: 431,332. Electric - lamp holders. GROTE, E. R., Spencer Hill Road, Wimbledon, London. Dec. 1, 1933, No. 33842. [Class 39 (ii)] In an electric lamp of the kind having an elongated tubular body provided with parallel unipolar lamp caps cemented to the body to cover a sealing point for a leading-in wire the cap is bifurcated to provide a resilient connection between holding- means, and its free end is electrically connected to its respective leading-in wire. As shown in Figs. 1 and 2 the cap 2 is provided with a flare 3 and a flat flange 4 formed with a rim 5 to provide a bed for cement 6 which secures the cap to the wall 7 of the lamp body in the manner described in Specification 431,376. Preferably the cap is slotted transversely and obliquely, the slot 9 opening to one side of the cap at the bottom to leave a cup 10 for the solder which secures the outer end of the leading-in wire 1 in the tapered lower end of the cap. The cap may be of circular, oval, or other cross section, and may be formed from a drawn tube or sheet metal, the stem portion 2 being of sufficient internal diameter to leave a space around the pip 8 of the tubular envelope 7, so that the strain of holding the lamp in a support is not transmitted to the pip. To ensure the retention of the cap in its holder the stem is provided near its end with diametrically opposite grooves or indentations 15. The caps may be applied to lamps for use with holders of the kind provided with U-shaped contact clips as described in Specifications 427,009 and 426,950, the limbs of the clip, however, being made rigid. Alternatively the lamps may be mounted with their caps in holders consisting of moulded insulating-blocks 12, Fig. 8, within which conducting wires 11 and short rigid wires 11<a> are embedded on opposite sides of apertures 13, the wires being so arranged that they grip and retain a lamp cap inserted between them. Fig. 9 shows a modification wherein the short rigid retaining-wire 11<a> is constituted by a branch of the conductor wire 11. The blocks are mounted in spaced pairs to receive a lamp, the wire between the blocks being encased in insulating sleeving 17 which is preferably placed in position before the blocks 12 are moulded around the wires. Bosses 16 and recesses 21 on the moulded blocks serve to increase the insulation between the wires 11. Specifications 304,882, 336,418, [both in Class 39 (ii)], 411,849, and 411,957 also are referred to.

Title: Improvements in or relating to railroad crossing signals
IPC: B61L29/28
Filed: 1929-11-09
Abstract: 344,877. Railway crossing signals. ENGLEHORN, E. H., 4605, Forest Drive, New York, U.S.A. Nov. 9, 1929, No. 34272. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 11, 1929.] [Class 105.] Lamp signals ; audible signals ; track apparatus actuating signals other than on trains.-A railway crossing signal automatically operated on the approach of a train comprises one or more gaseous conductor tubes 10 which are illuminated to simulate lightning and may be enclosed in a casing 8 having a zig-zag opening and be flashed sequentially. A siren 4 may additionally be interruptedly energized to give a wailing sound. The power is normally obtained by a step-down transformer 15 from a power line 12, but on failure thereof a local battery 13 is brought into service by the dropping of armatures 17 of a relay 16 energized by the transformer. The low-voltage current drives a motor 22 for actuating the rotary interrupter switches 24, 25 of the siren and of the gaseous conductor tubes ; energizes the siren 4 ; and supplies the primary windings of interrupter sparkcoils 30 which provide the high voltage for the gaseous conductor tubes. The signals are put into action by the train shunting track relays 41, 43 the armatures of which open the holding circuits of relays 20, 21 which normally are energized by the local battery 13 ; the dropping of the armatures of these last relays closes the circuits to the motor and to the gaseous conductor tubes and siren. The siren is shut off when the train shunts the relay 43 since the relay 20 is then re-energized.

Title: Change-speed mechanism
Filed: 1932-12-03
Abstract: 408,059. Variable speed gearing. RIDLEY, J. C., Wroxall, Priory Road, Kenilworth, Warwickshire. Dec. 3, 1932, No. 34274. [Class 80 (ii).] Striker-rods 12 of a four-speeds and reverse gear, which may be synchromeshed, are moved into operative positions by fluid-pressure under control of a distributing-valve which is preferably preselective, and are, prior to a change, all moved to the neutral position by fluidpressure means which is independent of the control valve. The neutralising-means comprise a pressure-cylinder 16, the piston of which acts on a pivoted lever 17, linked to pins 14 slidable in slots 13 in all the striker-rods 12. Pressure-oil supplied to the cylinder 16 causes both pins 14 to move inwardly against the tension of a spring 22 and bring the striker-rods to the neutral position. Each striker-rod 12 is moved to either operative position by a rod 25 rigidly connected to the striker-rod, and actuated, with lost-motion, by pistons 24 in cylinders 23 at each end of the rod 25. Springs 27 are arranged between the pistons and the rod 25. The fluid-pressure may be generated by a pump or by actuation of the main control such as a main clutch or other pedal 33, Fig. 5. After preselection of the required speed by a simple, ported, rotary distributing-valve, Figs. 3 and 4 not shown, the pedal 33 is depressed, first causing movement of a piston 38 to supply pressure-oil to the neutralizing cylinder 16. When the piston 38 reaches the limit of its travel, the neutralizing-pressure is released through a port 42. The pedal-plunger 32 thereafter moves a piston 35 to supply pressure-oil to the preselected cylinder 24 and engage the gear. In a modified main control, the neutralizing and gear-engaging pistons are moved simultaneously, the lost-motion between the rod 25 and its pistons being relied upon to ensure that the gears are neutralized before engagement. In both forms, neutral can be introduced at any time, irrespective of the position of the selector control-valve, by a partial depression of the pedal 33. Spring-loaded balls such as 43 locate the striker-forks 11 and also the selector-valve in various positions. The Provisional Specification states also that the change-speed gear may have a free-wheel or dog-tail clutch.

Abstract: 1324779 Flying shears M L LEVY 15 July 1970 [18 July 1969] 34381/70 Heading B3W In a machine for effecting an operation on a moving product, e.g. a flying shear, the machine having a product drive 16, a tool 5 and a tool drive 8, the speed of the tool is matched with that of the product by means of two unidirectional clutches 13, 27, Fig. 3 linked to the product drive one of which, 13, is linked directly to the tool so that the tool speed cannot exceed that of the product and the other, 27, is linked to a lever 24 having a can follower 23 which is associated with a cam 22 linked to the tool such that the tool is accelerated from rest to the product speed over the same distance irrespective of the product speed. This is ensured by the angular velocity of the lever 24 being prevented from exceeding that of the unidirectional drive 27 during acceleration of the tool. The geometry of the cam surface 22 and the lever 24 is such that as the tool reaches the speed of the product the cam follower 23 slows and the clutch 27 is disengaged. At the same time the clutch 13 is engaged by the direct link with the tool (via a rack 9 and pinion 10 as shown in Figs. 1 and 3) to prevent the tool speed exceeding that of the product. Thr product drive is by means of pinch rolls 2 and the product passes through a straightener 3 to the tool 5. The tool drive may be a fluid piston and cylinder assembly as shown in Fig. 1 or a fluid or an electric motor. A pulse generator driven by e.g. a measuring roller 7 initiates each cutting cycle.
